If you suffer from certain diseases during pregnancy, you have to do a CT or X -ray examination. Do you have to endure the pain or give up your baby? Pregnant mothers and family members often choose in pain.During pregnancy, I have radiated image tests such as X -ray or CT. Do you have to give up your baby?
First, it depends on pregnancy time.Week 8-15 is the most sensitive period for radiation. During this time, if the pregnant woman is exposed to the high-dose radiation scenario, the risk of the fetus with deformity or mental development will increase significantly.big.
Secondly, it depends on the amount of radiation.In fact, X -rays are not as terrible as ordinary people think.Studies have shown that after contacting 0.5 Rader’s irradiation, the chance of adverse effects only increased by thousands of thousands of tenths on the basis of the original risk, that is, about one fetus with a dose of X -ray radiation per 6,000There is a bad situation.
Finally, it depends on the inspection site.After pregnancy, most of the X -ray, or even CT examination, the uterus was not directly illuminated, and the fetal radiation was small.Because the fetus is always protected by the mother across amniotic fluid across the uterus.
Due to the deeper and ingrained fears and cognition of X -ray and the harm, many patients and medical staff have a lot of concerns and doubts about the imaging examination of pregnant women.
In addition, women’s use of ultrasound and magnetic resonance imaging during pregnancy and lactation (MRI examinations and competes are really safe and harmless, which also makes many people feel confused and worried.
In response to the above situation, the American Academy of Obstetrics and Gynecologists (ACOG) jointly released the latest version of the "Guidelines for the Diagnostic Imaging Examination of pregnancy and lactation" in February 2016 in February 2016
X -ray, radiation is not terrible
1. X -ray and radiation
The X -ray is an electromagnetic wave with a very short wavelength and a large energy. Its main harm is that the body tissue can produce an ionization effect.Because embryos and fetuses are more sensitive to X -ray exposure, people have a deep -rooted fear and concern about the X -ray examination of pregnant women.
According to research, the risk of fetal exposure to X -ray is related to the age and radiation dose when exposed. For the early development of embryos, the exposure of X -ray exposure (> 1 GY) can cause embryonic death.
In addition, high -dose X -ray exposure may also cause limited growth of fetus, small head deformity and intellectual obstacles.However, in the actual diagnostic imaging process, even multiple X -ray examinations can rarely achieve the threshold dose that can cause the above hazards.
The diagnostic X -light cannot hurt the fetus.In terms of medicine, X -rays are divided into two types, one is diagnostic X -ray, such as lung X -ray examination and dental X -ray examination; the other is the treatment X -ray, such as cancer radiation therapy.Radial measurement unit Rader, according to the instructions of the US radiology in the United States, the radiation dose is below 5 Radder, which will not threaten the developing embryo.
In other words, only one diagnosis examination will not endanger the health of the fetus.The diagnostic X -ray other than the abdomen has a small radiation of the fetus, such as the radioactive dose of the chest X -ray less than 0.05 Rad.The modern radiation instrument almost does not cause diffusion. X -rays are only exposed to the necessary parts, and they will not enter the body through blood and spread to the whole body.
Even if the diagnostic X -ray ejaculation, the risk is far lower than the scope of the pregnant mother’s worry.If the pregnant mother illuminates the lower part of the spine or abdomen, the X -ray dose received by the fetus in the abdomen is about 0,4 Rud.However, some diagnostic X -ray tests may have high radiation doses because it can use X -ray beams.If the pregnant mother needs to use the diagnostic X -ray for examination, the dose may exceed the safety range, and they must choose carefully.
Pregnant mothers can rest assured now, using X -rays for examination normally, and controlling the safe dose will not hurt the fetus in the stomach.However, it is still necessary to remind the pregnant mother in the early pregnancy that the operator of X -ray may not know that the pregnant mother is pregnant; so the pregnant mother must explain her identity before doing a examination!
Since you are pregnant, you can use X -rays to check normally, so there is no problem during pregnancy. After a beautiful eyebrow asked the unit’s physical examination, can the baby be pregnant?Do I still need to answer this question?
